Outline of Final Research Achievements

In this study, by taking into account for a metal enzyme with a catalytic active site consisting of two or more base metals, which undergoes organic transformations under mild conditions, we found new organic transformations using metal clusters consisting of two or more base metals, capable of using concerted synergistic effect between metal atoms: highly difficult organic transformations such as chemically stable amide bond cleavage reactions, polymer synthesis by carbon dioxide immobilization, and environmentally friendly oxidation reactions with oxygen as the sole oxidant.

Academic Significance and Societal Importance of the Research Achievements

本研究により、安価で入手容易な卑金属の触媒的利用として、一つの分子内に複数の金属を集めた金属クラスター錯体による反応場形成が信頼性の高い触媒設計指針となりうることを明らかにした。生体内において複数の金属中心を有する金属酵素が穏やかな条件で様々な反応を促進している化学的理由を、合成化学的見地から明らかにした点で学術的に意義深い。また、卑金属の高度利用は我が国の元素戦略的観点からも重要であり、社会的にもインパクトの高い研究成果である。
